Hi all, While fixing the Thrift server in the post-880/1304 world (see HBASE-880 and HBASE-1304), I made a small but potentially significant semantic change:
If you create a Mutation with the 'delete' flag, it will issue the delete call: http://people.apache.org/~stack/hbase-0.20.0-alpha/docs/api/org/apache/hadoop/hbase/client/Delete.html#deleteColumns(byte[],%20byte[]) rather than: http://people.apache.org/~stack/hbase-0.20.0-alpha/docs/api/org/apache/hadoop/hbase/client/Delete.html#deleteColumn(byte[],%20byte[]) The reason is that the second call is a little confusing, take the following sequence of events: put: rowA, column:name <-- value1 ... time passes ... put: rowA, column:name <--- value2 if you issue the latter, deleteColumn() you will get 'value1' all of a sudden. This could surface bad or embarrassing data. So I made the call and you can't access 'deleteColumn' via the thrift API right now. If you need to delete specific cell versions (thus exposing older cell versions), lets talk, we can add a new API for it. Happy HBasing/thrifting! -ryan
